`LUMBER-DR|ER.`

PECIFICATION forming part of Letters Patent No, 367,458, dated August 2, 1887.

To (LZZ whom it maz concern:

Be it known that I, J AMES D. STANLEY, of Eastover, in the county of Richland and State of South Carolina, have invented certain new and useful Improvements in Apparatus for Drying Tinber, Phosphate Rock, and other Materials, of which the following is a specification, reference being had to the accompanying drawings, and to the let'ters of reference marked thercon.

In the aeeonpanying drawings, Figure 1 is longitudinal section of my invention. Figs. 2, 3, 4, and 5 are details, hereinafter specified. ga 6 is a perspective view of a further de:

Similar letters of reference indicate Similar parts in' the respective figures.

A is a plate-iron cylinder of any suitable dinensions for the purposes in view-say, six feet in diameter and thirty to sixty feet long. The cylinder A is provided at each end with a head, one head, a, being permanently secured to the cylinder by means of bolts which attach to the angle-iron b. The other head, c, is removably attached to the angle-iron b'. The angle-iron b', (see Fig. 3,) is provided with an annular groove, b, (shown in Figs. 1 and 3,) which receives an asbestus or other packing, against which the flat or plain inner surfaee of the head c fits. The head c is provided at its outer side` with strengthening ribs c'. (Shown in Fig. 2.)

The cylinder A is provided l with plates d, bolted to its exterior, in each of which plates is hinged a slotted eye, d', through a pair of which eyes passes a bar, c. (Shown in Fig. 4.) The head c is forced up to the angleiron b' by screw-eyebolts f, (shown in Figs. l and 5,) which eyebolts are tapped into the bars e' and enter conieal depressions f', forned in the head c.- The cylinder is provided at its lower side with a track, g, upon which cars h, which support the timber or rock to be dried, run. The cars are preferably made short, so that several may be coupled together to occupy the entire length of the cylinder. The track conmunicates at the end of the cylinder having the reno'vable head with a permanent track. The cars are constructed entirely of iron, and may be of any suitable 'make for the purposes in view, a car being "shown in perspective in Fig. G. PreferablyI construet each car with a* central bearingpoint, h', and with standards h, said standards being ronnded to conforn to the shape of the cylinder. here the cars are to be used for phosphate-rock, their bodies will have to be modified in shape. The ears are attached together by couplings i, each coupling having,

at each end two bolts, 73' i', the coupling being slotted, so that where two cars are coupled together they are firnly held in line.

Each car is provided with a section of pipe, k, attached to the bottom of the car by hangers k. These Sections of pipe are adapted to be coupled together between the cars, as shown at la'. The section of pipe attached to the first car, or that nearest the back end of the cylinder, is extended beyond the front of the car and conmunicates with a pernanent eseape-pipe, Z, secufed to the head a, said pipe being reduced in diameter at its outer end and provided with a valve, Z'. The pipe attached to the rear car, or that nearest the front end of the cylinder, is furnished with a union coupling, Z", by means of which a connection is made with a coil of steanrpipe, m, which leads to acoil within a furnace. At the up per part of the cylinder is an escape-aperture, a, which leads to a condenser, the con-' denser-pipe being provided with acock, 0. A delivery-valve is shown at the lower side of the cylinder by o'.

The operation is as follows: The ears having been coupled together in the nanner de seribed, and the timber, phosplaterock, or other naterial placed upon the ears, they are run into the cylinder, and the head c is closed. The coil m having been coupled with the pipes k of the series of cars, and the outer section of the pipe k. having been caused to enter the escape-pipe Z, superheated stean is admitted to the coil and car-pipes and escapes at l. The interior of the cylinder is t-hus brought to a high degree of heat, and the Work of drying the material placed upon the cars proeeeds, the vapor escapiug through the apertu're n to the condensing-pipe, .The drying having been completed, the head c is removed, the pipes are uncoupled, and the cars withdrawn.

Should it be desired to use the apparatus ICO for creosoting, oiling, or otherwise treating timber, the material to be used may be admitted through the aperture a and discharged through the Valve 0'.

l he cylinder is made of sufficient strength, and, if necessary, braced to withstand the requisite internal pressure. t l he cylinder is mounted upon a solid brick foundation, and is a ermanent structure in connection with the ermanent track.

The advantages of attaching the steam-pi pes to the carsinstead of having, them attached to the bottom of the cylinder are as follows: If the steam-pipes are attached to the bottom of the cylindegthe Water dripping from the ti inber or other material and accumulating on the bottom of the cylinder will cover the steanpipes, cause a Vapor to rise, and prevent the dry heat from coming' in contact with the material to be dried. At the same time the Water will have a tendency to cool the pipes, and thus prolong the time necessary to effectually dry the timber or other material. VVhereas,

"by attaching the stcam-pipes to the cars directly under the material to be dried and some six or eight inches above the bottom of the cylinder with the cars the cylinder will cool more rapidly, and, as the pipes will not be in the way, the cylinder can be more easily and quickly cleaned out and made ready for the next operation. 4

Having' describcd my nvention, I claim- A cylinder having a track, steam-pipes, renovable head, and escape-aperture, conbined With cars, each car being provided with a section of steam-pipe adapted to be coupled with the section on the adjacent car, the section on the rear car being also adapted to couple with the coil of pipe in the cylinder, and the section on the first car beingextended beyond the front of the car and adapted to enter the escape-aperture, substantally as set forth.

In testimony whereof I hereunto set my hand and seal.
